Gusaba
Kugeza ubu, ikoranabuhanga rya BGA ryakoreshejwe cyane mu rwego rwa mudasobwa (mudasobwa igendanwa, supercomputer, mudasobwa ya gisirikare, mudasobwa y'itumanaho), ikibuga cy'itumanaho (paji, telefone zigendanwa, modem), ikibuga cy'imodoka (abagenzuzi batandukanye ba moteri y'ibinyabiziga, ibicuruzwa by'imyidagaduro y'imodoka) .Ikoreshwa muburyo butandukanye bwibikoresho bya pasiporo, ibisanzwe muri byo ni imirongo, imiyoboro ihuza.Porogaramu zihariye zirimo kugenda-kuganira, gukina, kamera ya digitale na PDA, nibindi
Ibibazo
BGAs (Ball Grid Arrays) nibice bya SMD bifite aho bihurira hepfo yibigize.Buri pin ihabwa umupira ugurisha.Ihuza ryose ryatanzwe muburyo bumwe bwa gride cyangwa matrix kubigize.
Ikibaho cya BGA gifite imiyoboro myinshi kuruta PCB zisanzwe, kwemerera ubwinshi-buke, PCB ntoya.Kubera ko amapine ari munsi yubuyobozi, icyerekezo nacyo ni kigufi, gitanga uburyo bwiza kandi bwihuse bwibikoresho.
Ibigize BGA bifite umutungo aho bazajya bahuza nkuko umugurisha atemba kandi agakomera bifasha muburyo budashyitse.Ibigize noneho birashyuha kugirango uhuze inzira igana PCB.Umusozi urashobora gukoreshwa kugirango ugumane umwanya wibigize niba kugurisha bikorwa n'intoki.
BGA yamashanyaraziubucucike bukabije bwa pin, kurwanya ubushyuhe bwumuriro, hamwe na inductance yo hasikuruta ubundi bwoko bwa paki.Ibi bivuze byinshi byo guhuza imiyoboro no kongera imikorere kumuvuduko mwinshi ugereranije nuburyo bubiri kumurongo cyangwa ibipapuro.BGA ntabwo ibuze ibibi byayo, nubwo.
BGA IC nibigoye kugenzura kubera pin zihishe munsi yipaki cyangwa umubiri wa IC.Kugenzura amashusho rero ntibishoboka kandi de-kugurisha biragoye.Abagurisha BGA IC bafatanije na PCB bakunze guhangayikishwa cyane numunaniro biterwa nuburyo bwo gushyushya muburyo bwo kugurisha.
Kazoza ka BGA Package ya PCB
Bitewe nimpamvu zo gukora neza no kuramba, paki za BGA zizarushaho kumenyekana kumasoko yibicuruzwa byamashanyarazi na elegitoronike mugihe kizaza.Byongeye kandi, hari ubwoko bwinshi bwa BGA butandukanye bwateguwe kugirango buhuze ibisabwa bitandukanye muri PCB ikora, kandi hariho ibyiza byinshi byiza dukoresheje iri koranabuhanga, bityo rero dushobora gutegereza ejo hazaza heza dukoresheje pake ya BGA, niba ufite ibisabwa, nyamuneka twandikire.
